It sounds like your setObjectValue: method is being called, but is
your objectValue method? Which way round are they being called?
I have fully implemented the objectValue method conforming to the interface, added some NSLog statements in there to see if it ever gets called and it does not. Is there something special that I have to do to get this working.

Try using doubleValue instead. It seems that NSValueBinder (which is used when you bind to an NSTableColumn's "value" binding) prefers doubleValue to objectValue (i.e., doesn't bind to objectValue if the cell responds to doubleValue). If that doesn't work, try floatValue, intValue, etc.

Best wishes,
Hamish
